Under what circumstances should fog lights be used?
2 Answers
According to traffic regulations, fog lights must be turned on when visibility is between 100-200 meters. Here are some relevant details about fog lights: 1. How to turn on fog lights: Car fog lights are mainly divided into three types: lever-type, knob-type, and button-type. The front fog lights can be turned on individually; the rear fog lights can only be turned on together with the front fog lights and cannot be turned on alone. 2. Notes on fog lights: Fog lights are suitable for severe weather conditions such as heavy rain, fog, snow, or dust. The visible range of fog lights is about 100 meters. When visibility is below 100 meters, fog lights must be turned on, and the speed should be reduced. The main purpose of car fog lights is to make the vehicle visible to those behind. Rear fog lights are designed to be red for warning purposes. The illumination of front fog lights is not all-powerful; if visibility is below 30 meters, turning on the front fog lights may not be very effective. In such cases, it is necessary to pull over and turn on the hazard warning lights.
As an experienced driver with years behind the wheel, I primarily use fog lights in poor visibility conditions caused by severe weather. For instance, in dense fog, regular headlights' beams get reflected back by the fog, making it harder to see the road. That's when fog lights prove invaluable—positioned low with a wide beam pattern, they better penetrate the fog to illuminate the road surface while making your vehicle more noticeable to others from a distance. They're equally effective during heavy rain or snowstorms. Driving on highways or rural roads in rainy or foggy conditions without fog lights increases the risk of rear-end collisions. Remember never to use fog lights in clear daytime conditions, as they can dazzle oncoming traffic and create safety hazards. Once, while driving a mountain road at night when sudden thick fog rolled in, I promptly activated my fog lights, preventing a collision with a truck that had strayed into my lane. Fog lights are life-saving tools in critical moments—I advise novice drivers to familiarize themselves with proper usage timing but avoid overuse.
